Application filed February 18, 1920. Serial No. 359,599."

T all whom it may] concern:

Be it known that I, AUGUST W. JANSSON, a citizen ofthe United States, residing at Kent, in the county of Portage and State of Ohio, have invented a certain new and useful Improvement in Blank Carriers for HeadingMachines and the like, of which the following is a full, clear, and exact description.

This invention relates to a blank carrier employed in connection with heading machines and the like in conjunction with a cutter bar to carry the severed blanks laterally from the point of severance to the dies or other instrumenta-lity which operates on the blanks.

The chief object of the invention is to provide a carrier having a blank holding finger so mounted and operated that the carrier is more positive in action in the respect that it holds the blanks more effectively, permits greater speed, and is quieter in operation than the carriers heretofore employed. Other and more specific objects are to provide a construction which is easy to assemble and easyto take apart for repairs and the like, easy to keep clean and having less protruding parts than the prior devices, thus eliminating a source of danger to the operator.

The above and other objects are accomplished by my invention which is illustrated in the drawings, described in the Specification, and set forth in the appended claims.

In the accompanying sheet of drawings, Fig. 1 is a side elevation with parts in section of the preferred embodiment of my invention, illustrating the carrier mounted on acutter bar slidingly mounted in a portion of the machine which for convenience will be assumed to be a header; Fig. 2 is a bottom plan view of the carrier ban-Fig. 3-is a top plan view of the outer part of the carrier; and Fig. 4 is a diagrammatic or conventional view of a header in connection with which my invention has utility."

In the drawings represents a cutter bar adapted to be slidingly mounted in the stationary part of a machine such as a header 11 as illustrated in Fig. 4:, and provided at its inner end with a cutter 12'which cuts blanks from a wire or rod 13 (see Fig. 4) fed into the machine, and with the cooperation of the carrier conveys the blanks laterally to dies such as upsetting dies 14. The cutter bar is usually provided with a roller 15 (see Fig. 1) which engages'in a cam slot of a cam 16 which is reciprocated by suitable parts of the machine to move the cutter laterally inward and laterally outward in harmony with the blank operating parts. l f L To hold the blanks or sections when out off from the stock 13 by the cutter, and with the assistance ofthe cutter to carry them 'later-' ally to the dies 14, :a so-called carrieris utilized. which in this instance includes; a

carrier bar 17, which extends over the cutter bar 10, and as here shown, is'pivoted at 18 to the top of an upstanding arm 19 at the outer end of the cutter bar. Preferablythis carrier bar 17 "is channel shaped, as shown particularly in Fig. 2, aportion of thech'an nel groove which is on the underside of the bar ,being narrowed as shown at 20 to ;cooperate with the tongue of aguide block 21 mounted on the machine'as shown in Fig; 1.

Yieldable connecting means is provided between the inner portionsof the carrier bar 17 land cutter bar 10 to' yieldingly hold thecarrier bar down onto the lower I part of the'guide block 21, but nevertheless to permit the bar 17 to be swung upwardly, and though this connecting. means .may' assume different formsit is preferable in the form of a coil spring 22.

The part of the; carrier which holds the blanks tothecutter 12 while they are being carried laterally to the dies consists of a finger 23, preferably in the form-of a flat bar mounted so that it may be swung outwardly to release the blank when the latter is held by thev dies so that the cutter can be retracted. The manner in which thisrfinger is mounted and spring actuated'soas to function in the ,desired mannerforms an important part of the invention. In this instance the upperpart ofgthe finger is held by set screws 24 in a slot at the inner end of a finger block 25 whose outer portion is reduced in size to form a tongue 25?, and en'- tends into a slot at the inner end of the carrier'bar 17, in which slotthe finger block is pivoted as by means of a cross pin Cal swing about the axis of the pivoting pin 26, and in this instance this is accomplished by a plunger 27 which engages the upper part of the tongue of the block 25, and by a coil spring 28, both the spring and the major portion or" the plunger being located in a barrel 29, formed on the upper part of the carrier bar 17, and lying parallel to the body portion of the bar. An adjustable screw at the outer end of the barrel permits the tension of the spring 28 to be adjusted so that the desired pressure is exerted on the block.

It is to be noted that when the cutter bar is being retracted after delivering the blank to the dies, the finger block 25 swings on the aXis of the pin 26 a sufficient amount to allow the lower end of the finger to clear the blank. When this takes place the sprin 28 is compressed slightly, and then when the finger rides over the blank, the block and finger are immediately restored to normal position with respect to the cutter. It is to be noted also that when the block swings from normal position the point or end of the plunger rides over the inner face of the tongue of the finger block, increas ing the leverage through which the spring 28 acts, and thus increases the effectiveness of the spring without requiring any con. siderable movement of the spring. These are features which contribute to the efiiciency and durability of the carrier.

With the carrier above described, the objects stated in the early part of the speci-' fication are attained to a very highdegree. but nevertheless certain features may be modified in construction without materially, if atall. decreasing the effectiveness of the device as a whole,'and I aim to include all such modifications which fall within the scope of the appended claims.

Having described my invention, 1 claim;

1. In combination with a cutter and cutter bar, of a header and the like, of a car- 'rier co-operating with the cutter to hold lanks comp-rising a finger normally sup ported adjacent the cutter, a pivoted member supporting the finger,a support for said pivoted, member, and means extending lengthwise of said support and acting on said pivoted member to yieldingly resist its movement in one direction.

2. A carrier for use in connection with a reciprocating cutter and cutter bar comprising a carrier bar adapted to be supported on the cutter bar, a finger block pivotally supported on the carrier bar, a carrier finger supported by said block and a device yieldable in a direction lengthwise of the carrier bar and yieldingly resisting the movement of the block in one direction.

3. In combination with a cutter and cutter bar of headers and the like, of a carrier comprising a carrier bar connected to the cutter bar, a finger block having a carrier finger and pivotally connected to the carrier bar, and means yieldingly resisting the movement of the finger block and acting on the same through a leverage which increases as the finger swings away from the cutter.

4. In combination with a reciprocating cutter and cutter bar, of a carrier co-operating therewith and comprising a carrier bar connected to the cutter bar, a finger block movably connected to the carrier bar, a carrier finger supported by the block, and a spring pressed plunger on the carrier bar and movable in a direction parallel there with, said plunger engaging said finger block and yieldingly resisting its movement.

5. The combination with a reciprocating cutter and cutter bar of a carrier comprising a carrier bar pivotally connected at its outer end to the cutter bar, a finger block piv-otally connected to the inner end of the carrier bar and having a carrier finger normally adjacent the cutter, a barrel carried by the carrier bar, and a spring pressed plunger in the barrel and engaging the finger block to yieldingly resist pivotal unovement thereof.

6. In combination with a reciprocating cutter and cutter bar of a blank carrier comprising a carrier bar connected to the cutter bar so as to reciprocate therewith, a finger block carrying a finger normally adjacent the cutter and having a tongue pivotally connected to the carrier bar, and means engaging a portion of the tongue to yieldingly resist pivotal movement of the finger block on the carrier bar.

7. In a metal working machine, a laterally reciprocating cutter and cutter bar for severing stock into sections, a carrier for said cutter bar comprising a carrier bar connected to the cutter bar, yieldable means for holding the carrier bar normally in predetermined position with respect to the cut ter bar, a finger block pivotally connected to the carrier bar and having a finger with a portion normally adjacent the cutter, and a spring pressed plunger carried by said carrier bar and engaging a portion of said finger block to yieldingly resist its pivotal movement on the carrier bar.

In testimony whereof, I hereunto atfix my signature.

AUGUST W. JANSSON.
